I use a calling card called i-talk on my landline in KL, Malaysia for lower call charges. I typically put about rm150 (50usd) credit from a few cards every month and run it down at the month goes on. I had about rm80 credit on 9th April 2011, took a vacation, returned 19th, tried to use the 1800 873535 i-talk number, and found that the credit is zero (there was nobody in my house during those days). So how can i trust TM to not steel my credit? When i phoned TM twice (100, 2, 4, 2) about this, they said "wait a minute", then cut the line!, third time she tells me, "sorry, system not working, please phone back later". I've only (politely) asked, "can you tell me what happened to my rm80?". I'm using skype from now on.
